WGFM requested WGSE in January 2013 (SE(13)11) to stop studies in the band 960-1215 MHz. The band 870-876/915-921 MHz is already considered in ECC Report 200.
WGFM requested WGSE in September 2014 (SE(14)085) to initiate spectrum sharing studies in the frequency range 1656.5-1660 MHz for Telecoil Replacement Systems (TRS).

Use of SRD applications in cars in the band 5725-5875 MHz
|
SRD/MG_40
|
To carry out investigations concerning the use of SRD applications in the band 5725-5875 MHz in cars equipped with 5.8 GHz road toll equipment, RLAN use based on the 5.8 GHz SRD regulation (max. 25 mW) as well as co-channel ITS communications (5855-5875 MHz) - all applications operating under the existing SRD regulations.
The aim of these investigations is not to change the existing regulations, but to investigate potential problems when having all these applications implemented in the same car within close distance.

The car industry (Car-2-Car consortia) has confirmed that RLAN use in cars will be implemented as of 2017 based on the existing SRD regulations for the 5725-5875 MHz (ISM) band.
WGFM#85 also sent a liaison statement to ETSI and ASECAP to request investigating the in- and out-of-band interference properties of road toll 5.8 GHz technology and also investigate possible solutions to improve the performance of products and/or related ETSI standards.
Hence, in this context, this request for investigations could also result in relevant information for the road toll industry when improving DSRC systems.
Noting the interest from the car industry to use 25 mW RLAN in cars, these investigations may also help this industry when designing the installation of equipment in the car.
Reference document: SE24(16)067 (LS from WG FM)
Thesharing scenarios for usage in cars include:
- RLAN use with max 25 mW under the SRD regulation (ERC/REC 70-03 Annex 1, band 5725-5875 MHz) and road toll equipment (ERC/REC 70-03 Annex 5, band 5795-5815 MHz) as victim;
- Co-channel ITS use (5855-5875 MHz, as per ECC/REC/(08)01) as victim and RLAN use with max 25 mW under the SRD regulation;
- any other 25 mW SRD use (with various bandwidths) with ITS (5855-5875 MHz) as victim and road tolling (5795–5815 MHz) as victim.
Also RLAN/SRDs may be considered as victims if the concerned stakeholders wish to study also this scenario.
The analysis of these investigations should indicate whether there are potential challenges with these scenarios.
The analysis should also include detailed investigation whether the CSMA spectrum use of RLANs with 25 mW will detect the relative short road toll exchanges at road tolling stations, with the aim to evaluate the nature,likelihood, conditions and real impact of such interference, if any

UWB based vehicularaccess systems operating in the 3.4 - 4.8 GHz and 6 - 8.5 GHz frequency ranges.

SRD/MG_48
|
To carry out compatibility studies for UWB based vehicular access systems operating in the 3.4 GHz to 4.8 GHz and 6 GHz to 8.5 GHz frequency ranges.
This type of application can be divided in 3 categories:
• Category A: Vehicular access systems using triggered UWB transmission for proximity verification;
• Category B: Extended vehicular access systems using triggered UWB transmission for proximity monitoring;
• Category C: Vehicular access systems using periodic UWB beacons for proximity detection.
The vehicular access control system Category A and Category B are proposed to operate under the European UWB regulation without the requirements of an additional exterior limit. Category C is only deemed feasible without exterior limits which may require a revision of these limits during the studies.

Studies should take into account different environments provided by existing UWB systems under current regulations in these bands.
Technical parameters and proposed mitigation measures for the studies are given in the SRdoc TR 103 416 on Technical characteristics and spectrum requirements for UWB based vehicular access systems for operation in the 3,4 GHz to 4,8 GHz and 6 GHz to 8,5 GHz frequency ranges.

Wireless PowerTransmission (WPT) systems operating below 30MHz
|
|
The first studies will focus on Wireless Power Transmission (WPT) systems for Electric Vehicles (EV) operating in the frequency band 79 - 90 kHz.
These studies will support the work of CEPT CPG on its studies in relation to WRC-19 Agenda item 9.1, Issue 9.1.6.

Other frequency bands identified by CPG PTD for WPT for EV may be considered in the study.
In a second step, an extension of the study for other kinds of WPT systems/devices (other than EV) and for other frequency ranges e.g. 19-21 kHz, 58-62 kHz and 100-300 kHz could be expected. A possible extension target date could be September 2018.
ETSI is working on a second SRdoc (ERM System Reference document (SRdoc); Wireless Power Transmission (WPT) systems for WPT operating below 30 MHz, DTR/ERM-563) dealing on all other kinds of WPT systems than EV_WPT. This extension could support the ITU-R WP 1A/WP 1B work on other WPT ranges (Question ITU-R 210-3/1 and Draft ITU-R Recommendation SM.[WPT]).

Study on high power SRDs on the first RFID interrogator channel at 916.3MHz of the frequency band 915-921MHz

SRD/MG_07

To develop the conditions of implementation of NBN SRD in the first RFID interrogator channel centered at 916.3 MHz of the frequency band 915-921 MHz
|
S: 12-05-2017
T: 01-09-2018
|
The use of high power SRDs in the first RFID interrogator channel requires additional study, to consider whether NBN SRD can be operated at 500 mW (with APC) and duty cycle of 2.5% (with NAPs at 10% duty cycle). If this is not feasible, other possibilities such as the reduction in transmit power necessary for coexistence could be studied.
ETSI is developing SRdocs on various LPWAN technologies which may be considered as part of this WI when they are available.
